摘要： A method for coating metallic surfaces with aqueous compositions, wherein a silane-based aqueous composition containing at least one silane and/or a related silicon-containing compound and optionally additional components is treated further, for example, at temperatures above 70° C., in a pretreatment step without drying the coating, by using at least one aqueous rinse step after this pretreatment step and then performing an electrodeposition coating, in which at least one surfactant is added at least in the last rinse step of the aqueous rinse steps. Coated metallic surfaces are also described.
